How to save time and traffic upgrading with apt-proxy
Thu, 26 Jun 2008 08:00:00 GMT
June is Bandwidth Conservation Month (well, not officially, but let's say that it is), so if you have multiple machines running an
APT-powered Linux distribution such as Debian or Ubuntu, you should take a look at
apt-proxy, a utility that caches package downloads in a shared pool for all interested parties on your LAN. This saves you both the time and the bandwidth it costs to download the same updates for more than one computer.

approx
APPROX(8) System Manager's Manual APPROX(8)
NAME
approx - proxy server for Debian archive files
SYNOPSIS
approx [OPTION]...
DESCRIPTION
approx responds to HTTP requests made by apt-get(8). It maintains a cache of Debian archive files that have been previously downloaded, so
that it can respond with a local copy when possible. If a file not in the cache is requested, approx will download it from a remote Debian
repository and deliver the contents to the client, simultaneously caching it for future use.
Over time, the approx server cache will grow to contain multiple, unneeded versions of Debian packages. The approx-gc(8) program removes
these from the cache.
OPTIONS
-c file, --config file
Specify an additional configuration file. May be used multiple times.
USAGE
approx is invoked by inetd(8).
EXAMPLES
Suppose that a client machine's /etc/apt/sources.list file contains the following lines:
deb http://apt:9999/debian testing main
deb http://apt:9999/security testing/updates main
deb-src http://apt:9999/debian unstable main
In this example, apt is the hostname of the approx server machine on the local network. Each distribution, such as "debian" or "security",
is mapped to a remote repository in the approx server's configuration file.
For example, the approx.conf file on the approx server might contain the lines
debian http://ftp.debian.org/debian
security http://security.debian.org
The mapping scheme is very simple. If the approx.conf file contains the line
repository http://remote-host/initial/path
then any request to the approx server of the form
http://approx-server/repository/rest/of/URL
is rewritten to
http://remote-host/initial/path/rest/of/URL
when there is a "cache miss", and that file is cached as
/var/cache/approx/repository/rest/of/URL
(Note that the repository name on the left-hand side is not included in the rewritten URL unless it is explicitly mentioned in the right-
hand side's initial path.)
FILES
/etc/approx/approx.conf
Configuration file for approx and related programs.
/var/cache/approx
Default cache directory for archive files.
